Product details
Overview
AUR9713AGH from Diodes Incorporated is a synchronous step-down DC-DC converter delivering up to 1A output current with adjustable output voltage (1V–3.3V), 1.5MHz fixed switching frequency, and integrated PMOS/NMOS power switches. It operates from 2.5V–5.5V input, features automatic PWM/LDO mode switching, and targets space-constrained portable power rails in handheld electronics.
For engineers reviewing the AUR9713AGH datasheet, AUR9713AGH pinout, AUR9713AGH application, or AUR9713AGH equivalent, key selection criteria include feedback reference voltage (600mV), thermal shutdown threshold (150°C), UVLO hysteresis (0.1V), peak inductor current capability (1.5A), and TSOT-23-5 package compatibility with high-density PCB layouts.
Technical Context
The AUR9713AGH employs constant-frequency peak-current mode control with internal compensation, eliminating external loop components. Its synchronous rectification uses integrated 0.28Ω PMOS and 0.38Ω NMOS switches, enabling >90% efficiency at mid-load across 2.5V–5.5V input range.
Automatic transition between PWM and LDO modes maintains regulation down to 100% duty cycle under low-VIN/high-VOUT conditions. Built-in soft-start (typ. 2ms), UVLO (1.8V ±0.1V), and thermal shutdown (150°C) provide robust startup and fault protection without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1A continuous - supports single-core microcontrollers and RF transceivers without derating at TA ≤80°C |
| Switching Frequency | 1.5MHz (±20%) - enables use of 2.2µH inductors and 10µF ceramic output capacitors for compact footprint |
| Feedback Voltage | 600mV ±2.5% - sets output via resistor divider; allows precise 1V–3.3V adjustment with <±3% total accuracy |
| Input Voltage Range | 2.5V–5.5V - compatible with single-cell Li-ion (3.0–4.2V), USB VBUS (4.75–5.25V), and 3.3V/5V rails |
| Quiescent Current | 100µA - minimizes no-load power loss in battery-powered standby modes |
| Thermal Shutdown | 150°C - protects device during overload or poor PCB heat sinking; auto-recovery on cooldown |
| UVLO Threshold | 1.8V with 0.1V hysteresis - prevents erratic operation during brown-out and ensures clean startup |
Pinout & Package
Package: TSOT-23-5 - ultra-small surface-mount package (2.9mm × 1.6mm × 1.1mm) with exposed thermal pad for enhanced power dissipation in space-limited designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 EN | Enable control input | Active-high logic signal; pulls internal bias circuits; 1.5V min high-level threshold ensures noise immunity |
| 2 GND | Power ground reference | Common return path for NMOS switch and control circuitry; must connect directly to low-impedance system ground plane |
| 3 LX | Switch node | Connects to inductor; carries high di/dt switching current; requires short, wide trace to minimize EMI and voltage spikes |
| 4 VIN | Input power supply | Accepts 2.5V–5.5V; requires local 4.7µF low-ESR ceramic capacitor placed within 2mm of pin |
| 5 FB | Feedback input | Senses output voltage divider; high-impedance (30nA bias) node requiring direct routing away from LX and noisy traces |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Buck Topology | Integrated 0.28Ω PMOS + 0.38Ω NMOS switches eliminate external Schottky diode and reduce conduction loss by >30% vs. asynchronous design |
| Auto PWM/LDO Mode Switching | Maintains regulation at 100% duty cycle when VIN ≈ VOUT, extending battery runtime in low-dropout conditions without efficiency collapse |
| Built-in Soft Start | Typical 2ms ramp time limits inrush current into output capacitor, preventing input rail sag and system reset during power-up |
| Internal Compensation | Eliminates need for external Type-II/III compensation network - reduces BOM count and layout sensitivity while ensuring stability with 2.2µH–4.7µH inductors |
| Thermal & UVLO Protection | Independent shutdown triggers prevent latch-up during overtemperature (150°C) or undervoltage (1.8V) events; both recover automatically after fault clearance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2153GQ-Z (Monolithic Power) | Higher 2MHz switching frequency; 0.35Ω/0.55Ω MOSFET RDS(ON); no LDO-mode fallback | Requires smaller 1µH inductor but less tolerant of low-VIN/high-VOUT ratios; no 100% duty cycle operation | Select when board area is critical and input-output differential remains ≥1.2V; avoid for Li-ion discharge below 3.2V |
| TI TPS62231DRYR | 1.8V–6.5V input; 3.6V max output; 0.45Ω/0.65Ω RDS(ON); fixed 3.3V/2.85V/1.8V options only | Lacks adjustable output; higher quiescent current (25µA typical but no LDO mode); requires external compensation | Choose for fixed-voltage systems where BOM simplicity outweighs adjustability; verify loop stability with chosen inductor/capacitor |
Compared with MP2153GQ-Z and TPS62231DRYR, the AUR9713AGH uniquely combines adjustable output (1V–3.3V), true 100% duty-cycle LDO mode, and fully integrated compensation - making it optimal for battery-powered applications requiring wide input range, minimal external parts, and seamless light-to-heavy load transitions.

FAQ
What is the minimum recommended output capacitor for stable operation?
The AUR9713AGH requires a minimum 10µF ceramic output capacitor with ≤10mΩ ESR for stable operation across 1A load steps. Using lower capacitance or higher ESR risks overshoot, ringing, or thermal shutdown during transient loads - verified in Figure 8 and Application Note Section 2.
Can the AUR9713AGH operate with input voltage below 2.5V?
No - the absolute minimum input voltage is 2.5V per Recommended Operating Conditions (Table 2). Operation below this violates specification and may cause UVLO activation or unregulated output; the 1.8V UVLO threshold is a protection limit, not an operational floor.
How does the automatic PWM/LDO mode switching affect efficiency at light loads?
Below ~10mA load, the AUR9713AGH enters LDO mode, bypassing switching losses and achieving >85% efficiency at 1mA - significantly higher than PWM-only regulators. This is confirmed in Figure 7 (LDO Mode Efficiency vs. Load Current) and enables extended battery standby time.
Is the TSOT-23-5 package RoHS-compliant and halogen-free?
Yes - the AUR9713AGH "G" suffix denotes Green (RoHS-compliant and halogen-free) packaging per Diodes Incorporated's Product Definitions document, with lead-free matte tin plating and compliant molding compound meeting JEDEC J-STD-020 moisture sensitivity level 1.
